Description

Overview
The CS-L series is a linear pneumatic cylinder sensor that provides visible, live piston position indication via a full-length bar LED. It enables top-down installation without cylinder disassembly and fast configuration using a 2-point push-button teach. The sensor supplies piston position and impact-level data to support diagnostics and cycle-time optimization.

Main features
  • Full-length bar LED delivers live piston position visibility.
  • Simple 2-point teach (push-button) for quick setup with no alignment needed.
  • Top-down mounting allows installation/removal without disassembling the cylinder.
  • Outputs piston position and impact (shock) level for diagnostics and process control.
  • Standard: 2 outputs per sensor; optional 3rd output and advanced configuration via a high-functionality amplifier.

Details
The CS-L uses a visible bar LED to display piston position with fine resolution. Installation is performed from above into the cylinder groove, avoiding cylinder disassembly. Settings are created with a 2-point teach button and can be locked to prevent accidental changes. The sensor reports impact-level and stroke/time information to aid in early fault detection and process improvement. Wiring supports loose wires or M8 connectors; note that certain functionality requires the PNP M8 connector type. A separate high-functionality amplifier accessory enables adjustable set-point windows, the creation of a third output, remote configuration for hard-to-reach installations, and can be disconnected after setup if required.

Applications / Use cases
  • Real-time piston position monitoring for process setup and troubleshooting.
  • Position-based control or interlocks using taught set points.
  • Machine diagnostics using impact-level and stroke-time outputs.
  • Situations where cylinder removal for sensor installation is impractical.
